What is ActiveMQ? How does it work?
ActiveMQ is an open source protocol developed by Apache which functions as an implementation of message-oriented middleware (MOM). Its basic function is to send messages between different applications.
ActiveMQ translates messages from sender to receiver. It can connect multiple clients and servers and allows messages to be held in a queue, instead of requiring both the client and server to be available simultaneously in order to communicate. Messaging can still happen even if one application is temporarily indisposed.
In AE also, ActiveMQ works in the same manner as like messaging queue between server and agents.
